AQL inspection for chairs: what actually gets checked before shipment

You approved a great sample, you placed the order — and now 500 chairs are sitting in a warehouse about to ship. A pre-shipment inspection is your last chance to catch a problem before it's on the ocean. Here's how it works and what it should cover.

What "AQL" actually means

AQL — Acceptable Quality Limit — is a standard statistical method (ISO 2859) for inspecting a sample of a batch instead of every single unit. You don't open 500 cartons; you open a calculated number, and the standard tells you how many defects are acceptable before the batch fails.

Defects are usually graded:

• Critical — safety issues (e.g. a faulty gas lift). Zero tolerance.
• Major — a defect a customer would notice and return (wobble, broken adjustment, big cosmetic flaw).
• Minor — small cosmetic issues with a higher allowance.

You set the AQL levels (a common choice is 0 critical / 2.5 major / 4.0 minor). The inspector pulls the sample and counts.

What a good chair inspection covers

A proper chair inspection isn't just "do they look okay?" It should include:

• Function: every adjustment worked, height holds, recline locks, nothing rattles.
• Stability and safety: five-star base, gas lift markings/class, no tipping.
• Assembly fit: parts go together correctly, hardware complete.
• Cosmetic: stitching, mesh tension, foam, scratches, colour match to the approved sample.
• Measurements: key dimensions and weight against spec (a quiet check for thinner steel/lower-density foam).
• Packaging and labels: carton strength, barcodes, manuals, and units-per-carton — plus often a carton drop test for e-commerce.
• Quantity and loading: the right number of units, packed and ready.

DIY, third-party, or factory?

• Third-party inspection (SGS, QIMA, etc.) — independent eyes, you pay a few hundred dollars. Recommended for first orders or large runs.
• Factory self-inspection — a good factory inspects its own output anyway and shares the report. Useful, but it's the factory checking itself.
• Your own QC — if you have someone in-country.

For a first order with a new supplier, a third-party pre-shipment inspection is cheap peace of mind. For ongoing orders with a trusted factory, their own QC plus spot checks often suffice.

Why a good factory welcomes it

Here's the tell: a factory that's comfortable with inspection is a factory that's confident in its output. We run our own AQL checks and welcome third-party inspectors — it's far cheaper for everyone to fix a problem in our warehouse than to argue about it after it's landed in yours.

If you want an order inspected against your approved sample — yours, a third party's, or ours plus a shared report — tell us at [email protected] or through the site, and we'll build the inspection into the plan.
